Which ProFlex Commander Option Should You Choose?
Standard Commander
The Standard Commander is the go-to choice for stock or lightly modified vehicles running factory fuel injectors and naturally aspirated setups. If you haven’t upgraded your injectors or added forced induction (like a supercharger or turbo), this is the perfect fit.
- No tuning required
- Seamless flex fuel performance
- Ideal for street-driven and daily performance builds
Commander Pro
The Commander Pro is built for high-performance builds with upgraded fuel systems. If your vehicle has (or will have) aftermarket forced induction or larger fuel injectors (600cc / 60 lb/hr or bigger), the Pro is your move.
- Works with your current setup — and scales as you upgrade
- Recommended for turbocharged or supercharged builds
- Features more precise injector management for controlling big injectors.
Bottom line:
Got boost or big injectors? Go Pro.
If not, the Standard is all you need.
Which Fuel Sensor Do You Need?
Standard Sensor
The Standard Sensor delivers rock-solid ethanol content readings and is great for most stock or mildly modified fuel systems.
- Accurate ethanol % readings
- Reliable performance for daily and spirited driving
- No extra bells and whistles — just works
E-Sense Sensor Upgrade
The E-Sense is designed for modified fuel systems where precision and performance matter most.
- Higher flow capacity for high-horsepower builds
- Adds fuel temperature monitoring
- Unlocks real-time data in the ProFlex Connect app
Rule of thumb:
If your fuel system is stock, go Standard.
If it’s modified, go E-Sense.
The ProFlex Commander product line is backed by a limited 12 month warranty. Learn more.
